DAVID Cameron has warned Britain's reputation will be damaged around the world if MPs fail to back airstrikes against Islamic State (ISIS) terrorists in Syria.

David Cameron said Britain would be damaged if MPs did not back airstrikes

The Prime Minister is making fresh calls to MPs to vote in proposals to bomb ISIS with air strikes in Syria, after previously being denied.

The Prime Minister also signalled he will fast-track a Government bill handing security services greater powers to snoop on communications between extremists in the wake of the Paris terror attacks, which killed 129 people.

Mr Cameron is currently attending a G20 meeting of world leaders in Turkey, where discussions will be dominated by global efforts to wipe out ISIS-inspired terrorism following Friday's nights atrocity in the French capital.

Over the weekend, France struck back against the brutal jihadist group with their most severe airstrikes to date against the extremists in Syria.

However, British forces are unable to take similar action against ISIS (or ISIL) strongholds in Syria after MPs previously failed to back military action in the country.

Despite recent reports suggesting he had dropped plans to ask MPs to authorise RAF bombing raids in Syria, the Prime Minister expressed frustration Britain's Typhoon jets are able to target ISIS in northern Iraq but not over the country's border.

He told BBC Radio 4's Today programme: "ISIL don't recognise a border between Iraq and Syria and neither should we.

"But I need to build the argument, I need to take it to Parliament, I need to convince more people.

"We won't hold that vote unless we can see that Parliament would endorse that action.

"To fail on this, it's not a case of damaging the Government it's a question of not damaging our country and it's reputation in the world.

"I will build the case but in the end Parliament must decide."

Mr Cameron urged a "full-spectrum response" to the threat of radical and violent Islamism, which he described as "the struggle of our generation".

The world has united in an act of solidarity in tribute to the victims of the Paris terror attacks. Landmarks around the world have been lit in blue, white, and red to symbolise the French flag.

Boris Johnson supported Mr Cameron’s calls for air strikes in Syria, telling LBC radio this morning: “You have to wonder if the price of not doing something is going to be higher than the price of action.

"You have to wonder how long we can let them go on with it."

He also supported Mr Cameron’s plans to fast-track the Investigatory Powers Bill to boost counter-terrorism.

Also dubbed the 'Snooper's charter' by critics, the bill would allow police and security services to access the internet browsing history of everyone in the country.

He said he has "less and less sympathy with those who oppose the new surveillance powers that the Government would like to give the security services".
